Square Yard (yd²)
The square yard, or yd², is an area unit from the imperial system. It is the area of a square with one-yard sides and equals 9 square feet or 0.836127 square meters. Used first in England, the square yard was set as a standard in the 1900s. It is still used in the US and UK, particularly for real estate, carpets, fabrics, and sports fields. While most of the world now uses square meters, the square yard is still recognized and used in certain professions.
Square Foot (ft²)
The square foot (ft²) is a standard unit of area in both the imperial and US customary measurement systems. Defined as the area of a square with each side measuring one foot, one square foot equals 144 square inches or roughly 0.0929 square meters. Its origins date back to the Middle Ages, and it eventually became a fixed standard. Today, the square foot remains a popular unit in the United States, Canada, and the United Kingdom, especially for describing the size of residential and commercial spaces. Although metric measurements are more widely adopted worldwide, the square foot continues to be important in real estate and construction practices within these countries.
